IBDM is not available for OpenIB as yet and the OpenIB diagnostics have
been in place for a while now. 

Also, as far as I know, no one outside of Mellanox has looked at this.
So that would be a next step. 

Is there any documentation on IBDM ?

Also, are there updates to this or is the version in the tree what
should be looked at (and commented on) ?

By using the comment fields appropriately with semantics for logical
hierarchy.

Yes.

IMO that was not the case. I don't have the time to go dig these back
out right now.
